Allow me to point you to the FujiFilm Minilab, a machine I am quite familiar with. It is not by any means a "niche" solution, yet not even 10,000 of them have been produced. These machines are found everywhere, from Walmart's to Wolf Cameras. By your definition of "niche" you would exclude the most produced photo-finishing machine on the planet. As everyone that takes snapshots needs them developed, a good percentage run through a Fuji built minilab.
